Cheapest best XBMC box available for 1080p and fluid browsing?

I have an Apple TV 1 with BCHD15 and Crystalbuntu 2, as well, and I'm calling BS on those claims :)

Its right in front of me right now and I can tell you that it either shows a blank screen or shows artifacts with Hi10P content.

When I was with CB1 my ATV wont play 10bit, it used to show a black screen, but when I updated to CB2, SUDDENDLY it start to play 10bit content...

Can I upload an anime episode ["Ben-To", episode 01, 10 bits, 720p, 167MB ] ?

Or can you upload the file you want in 10 bits? And I record my ATV playing?

Why my ATV play 10 bit content? I dont know.

This is the BCHD card that I have, from this EXACTLY seller.
eBay BCHD Link

If you want I can also run tests, post logs, etc...

EDIT: add info.

I got the last episode from ARROW, and had encoded into 10 bits myself.
x264 64bit 10bit-depth encoder from 'x264.nl'
And used this settings on '.bat' file:

" x264-10 --preset veryslow --tune animation --crf 18 -o %1.[10bits].mkv %1 "

and my ATV played fine, this time without frame skips [ I think it is because of the resolution, 480p w/o frame skips, 720p with some...]

Tested another file, this time with a soap-opera from Brazil [Flor do Caribe] encoded with the same settings.
